APPENDIX A.4O: Advanced Metallurgical Assessment of the Casino Copper Gold Project

ADVANCED METALLURGICAL ASSESSMENT OF THE

CASINO COPPER GOLD PROJECT

WHITEHORSE, YUKON

KM3512

December 20, 2012

Work Performed on behalf of Western Copper and Gold Corporation

1

1.0 Introduction

Western Copper and Gold Corporation is currently conducting a feasibility

assessment of the Casino Project, located 300 kilometres northwest of

Whitehorse, Yukon. The deposit is described as porphyry mineralization with

geological zones of oxide, supergene, and hypogene mineralization.

Previous test programs have developed a flotation process to extract a bulk

copper-molybdenum and gold concentrate. This program of study was intended to

produce tailings samples for environmental testing and investigate the copper-

molybdenum separation process. The program also provided an opportunity to

evaluate the process using fresh hyrogene drill core. Many of the previous test

programs had been conducted on core sample that had been in storage for a long

time and could have possibly oxidized.

This study was commissioned at the request of Dr. Paul West-Sells, President and

CEO at Western Copper and Gold Corporation. On behalf of Western Copper

and Gold Corporation, Mr. Jeff Austin of International Metallurgical and

Environmental provided technical input on the design of the program. The

objectives of this program, as described by Mr. Austin, were as follows:

- Prepare six composites for laboratory and pilot scale testing; three

composites representing geological sub-types of the hypogene zone were

designated for laboratory testing. Two separate composites of hypogene

and supergene fresh drill core sample were prepared for pilot scale testing.

A third commissioning composite for the pilot plant was also prepared

from old reject sample.

- Evaluate the metallurgical performance of the hypogene composites using

batch and locked cycle flotation tests.

2

- Process the pilot composites using the developed flowsheet. From the

pilot testing, obtain samples of tailings and concentrate for subsequent

testing.

- Conduct preliminary copper-molybdenum testing on the concentrate

produced from the pilot campaign.

- Assay the concentrates for minor payable and deleterious elements.

The following technical brief summarizes the key technical points of the program.

All of the test data generated through the execution of this program can be

reviewed in a series of appendices attached to this brief. The appendices are

arranged as follows:

Appendix I - Sample Origin

Appendix II - Flotation Test Data

Appendix III - Particle Sizing Data

Appendix IV - Special Assay Data

Appendix V - Pilot Plant Data

2.0 Properties of the Hypogene Composites

The chemical content of composite samples were determined by standard

assaying techniques. The results are summarized in Table 1.

Copper averaged about 0.17 percent for all of the composites. This grade was

slightly lower than some of the other samples previously investigated. Weak acid

soluble copper was low for the hypogene composites, averaging about 3 percent

of the total copper. This level is very low, indicating the samples should respond

well to the developed copper flotation process.

Gold in the samples ranged between 0.18 and 0.22 g/tonne. Molybdenum in the

sample was relatively high ranging from 0.019 to 0.071 percent by weight. The

high relative levels of molybdenum to copper should result in high levels of

molybdenum in the bulk copper concentrate.

The IX and WR samples averaged about 2.3 percent by weight sulphur.

Comparatively, the PP Composite had relatively low levels of sulphur. Although

no mineralogical analyses were conducted, past programs would suggest that

pyrite would account for most of the remaining sulphur in the sample.

On this basis, anticipated pyrite levels in the IX and WR Composites would be

high relative to the copper sulphides in the sample. Careful control of flotation

pulp conditions will be required to optimize pyrite rejection from the concentrate.

3.0 Flotation Testing – Hypogene Composites

3.1 Rougher Test Results

A total of 14 rougher flotation tests were conducted in this program. The

tests were used to establish the initial response of the composites using

previously developed flotation conditions. Primary grind size and rougher

pH were the two primary variables investigated. A summary of the test

conditions and a graphical display of the results are shown in Figure 1.

The following conclusions were reached when reviewing the test data:

The results indicated that there was a negligible effect of primary

grind size on copper rougher flotation response over the range of

primary grind sizes tested; 150µm to 250µm K80.

For the hypogene composites, copper in the feed was about 88 to

95 percent recovered into the feed at a rougher mass recovery of

about 8 to 10 percent. The performance of the samples appeared to

be better than previously tested samples despite lower feed grades*.

Rougher pH appeared to have an effect on the metallurgical

performance. Tests conducted at higher pH had better rougher

response curves. It is assumed that the pyrite in the feed was better

depressed at higher pH allowing more aggressive copper sulphide

flotation.

Molybdenum recovery to the rougher concentrate was also highly

variable. The samples had superior performance when compared

to the other composites. Molybdenum was about 80 percent

recovered from the feed into the rougher concentrate at 9 percent

rougher mass recovery. Molybdenum flotation data is graphically

displayed in Appendix IV, Figure IV-1.

Gold recovery data was not generated for the rougher tests.

* Quantitative mineralogy on ground feed samples should be conducted to determine if the fragmentation properties were morefavourable for these samples.

3.2 Cleaner Test Results

Based on the latest flowsheet configuration testing*, batch cleaner test

utilized regrind on the first cleaner concentrate. The flowsheet is

presented in Figure 2 along with a graphical presentation of the

metallurgical results. The tests also investigated a lower pH in the cleaner

circuit in an effort to improve molybdenum recovery.

As shown in the top graph of the figure, copper grade and recovery

performance was negatively affected by the reduction of pH in the cleaner.

For molybdenum, there was no clear benefit to metallurgical performance

by operating at a lower pH. It was, therefore, recommended to perform a

locked cycle test at pH 11 in the cleaner circuit.

A series of tests on IX Composite were performed to optimize the

chemical conditions for the first cleaner regrind (Test 22) and a

comparison to rougher regrind (Test 21). Both tests indicated an

improvement in metallurgical performance for copper and molybdenum

over the baseline test. Test 21 also indicated a slight metallurgical

performance gain with the rougher regrind circuit. The operating and

capital cost will be higher for the rougher regrind flowsheet compared to

the first cleaner regrind circuit. Further testing would be required to

confirm these test results.

3.3 Locked Cycle Test Results

A series of locked cycle tests were conducted in this program to establish

the estimates of metallurgical performance anticipated from a continuous

process. Both the first cleaner regrind and rougher regrind flowsheets

were tested in locked cycle for all three composites. Figure 3 displays the

rougher regrind flowsheet schematic used in these samples, along with a

summary of test results.

The first cleaner concentrate regrind data is displayed in Appendix IV,

Figure IV-2. Overall the first cleaner regrind cycle tests did not perform

as well. The reagent dosages in these tests did not appear to be full

optimized as losses of copper were high in the cleaner tailings streams.

Overall, the metallurgical performance of the rougher regrind flowsheet

was very good. Copper in the feed was 89.9, 87.2 and 91.9 percent

recovered into the bulk concentrate for IX, PP and WR Composites,

respectively. The concentrate grades range between 18 and 25 percent

copper. The concentrate grades were lower for IX and PP samples due to

high levels of molybdenum in the concentrate. The WR Composite was

also lower due to higher levels of pyrite*.

Similarly, molybdenum was 78, 79 and 89 percent recovered into the bulk

concentrates. Molybdenum grade ranged from 7.5 to 1.5 percent. Finally,

gold recoveries ranged from 55 percent to 67 percent to the bulk

concentrate.

The apparent use of recently drilled sample has resulted in arguably better

overall metallurgical performance. Additional mineralogy on these

ground feed samples should be performed to verify that the copper and

molybdenum characteristics for these samples are similar to previously

tested composites. If the characteristics are the same, this would increase

confidence that a gain in metallurgical performance will be realized by

treating fresh ore.

* The sulphur grades are high on this concentrate, perhaps indicating higher levels of pyrite.

4.0 Pilot Plant Testing

Pilot plant testing was performed on three composites of Casino mineralization.

The initial pilot plant calibration was conducted on a composite constructed from

old sample from previous programs. The main campaigns were performed on two

composites constructed from fresh drill core sample. The samples represented

hypogene and supergene mineralization. Pilot runs P2 and P3 were on the PP

Hypogene Composite, runs P4 and P5 were completed on the PP Supergene

Composite.

The primary objective of the pilot campaign was to produce tailings for

environmental studies. Concentrate form the program was also used to

investigate separation of copper and molybdenum. The flowsheet used to process

the sample is shown in Figure 4, along with a summary of conditions and results.

The primary mill was operated at a nominal 100 kg per hour; copper rougher

flotation was performed in 6, 12 litre flotation cells. Pyrite flotation was

conducted in another 6, 12 litre cells. Rougher concentrate was reground in a 2

litre IsaMill and graded in a conventional first cleaner and column cell cleaner for

stages two and three.

Overall, the performance copper flotation circuit never stabilized. Copper

recoveries from the feed to bulk concentrate ranged between 73 and 87; however,

the concentrate grades were very low. The concentrates were very high in iron

and sulphur, indicating pyrite as the principle diluent.

The pyrite circuit used Potassium Amyl Xanthate (PAX) as the primary collector.

The collector dosages were high to produce a low sulphur tailing required for the

environmental sample. The PAX dosages were not optimized and it was likely

that PAX was recycled to the copper circuit as part of the tailing water recycle.

Elevated levels of PAX in the recycle would cause activation and flotation of

pyrite in the copper circuit.

5.0 Copper – Molybdenum Separation

The concentrate from the pilot plant was retreated to remove excess pyrite ahead

of copper-molybdenum testing. This work was reported in pilot runs P6 to P8.

While the concentrate grade improved, the bulk concentrate would be considered

low grade.

Despite the lower concentrate grade, the bulk concentrate from the P6 to P8

campaigns was combined and a single cleaner test was conducted to evaluate the

copper-molybdenum process. Conventional copper depression with Sodium

Hydrosulphide (NaHS) and flotation with nitrogen was conducted. The

flowsheet, reagent conditions and metallurgical balance for the test is displayed in

Figure 5.

As shown, the concentrate produced contained low levels of copper and was high

grade. Molybdenum was 94 percent recovered into a concentrate grading 51

percent molybdenite. This data indicates the molybdenum would respond well to

a conventional molybdenum separation process.

6.0 Quality of the Concentrates

The minor element concentrations of the concentrates were measured with

element specific analyses to increase the accuracy. The results of the analyses are

displayed for the composites tested by locked cycle in Table 2. To have sufficient

sample to assay, cycles IV and V were combined. The following comments may

be relevant when reviewing the table:

- The bulk concentrates for some composites showed elevated levels of

arsenic, lead and zinc. However, none of the levels measured would cause

a significant barrier to marketability.

- Silver levels in the bulk concentrate ranged from 82 to 126 g/tonne. At

these levels, payment of silver might be possible.

- The molybdenum concentrate was relatively free of deleterious elements.

Arsenic, lead and zinc may be elements to reassess when more

molybdenum concentrates become available. Rhenium in the concentrate

was 134 g/tonne. See Appendix IV-Special Data for the Rhenium

Certificate.

- Fluorine assays were not reproducible and therefore not reported.

Additional fluorine assays should be conducted when sample becomes

available.

- The minor element data should be reviewed by a specialist to provide

specific advice on the current concentrate market.

7.0 Conclusions and Recommendations

The testing of three hypogene composites produced very good metallurgical

performance, despite relatively low copper feed grades. On average, copper was

90, 87 and 92 percent recovered into bulk concentrates for the IX, PP and WR

composites, respectively. The concentrate grades were within expected ranges

considering the high levels of molybdenum in the bulk concentrate. The WR

Composite had lower concentrate grade perhaps due to pyrite.

Molybdenum was also well recovered to the bulk concentrate at 78, 79 and 89

percent for the IX, PP and WR Composites, respectively. The high relative grade

of molybdenum to copper in the feed resulted in concentrates containing between

1.5 and 7.5 percent molybdenum in the concentrate. The gold in the feed was 57,

55 and 67 percent recovered to the bulk concentrates for IX, PP and WR

Composites, respectively. These results were in line with previous results.

The metallurgical performance of these fresh drill composites were better than

previously tested hypogene composites constructed of old drill core sample.

Mineralogical assessment of the ground feed samples is recommended. If the

fragmentation properties are similar to previously tested samples performed on

old core, this would increase confidence that these latest results should be

expected when treating fresh ore.

The best metallurgical results (quoted above) were produced with a rougher

regrind flowsheet. The first cleaner concentrate regrind circuit locked cycle tests

produced inferior results; however, the tests were not fully optimized for reagents

in the cleaner circuit. This first cleaner regrind circuit has lower capital and

operating cost and, as previously shown, can provide similar metallurgical results

when fully optimized.

The pilot recessing of the hypogene and supergene composites was completed to

produce tailings sample for environmental testing. This objective was effectively

completed with the addition of a pyrite rougher circuit after the bulk copper-

18

molybdenum and gold circuit. Tailings samples of each composite were shipped

to the required third party testing groups.

Unfortunately, there was insufficient sample to stabilize bulk concentrate

production for subsequent copper and molybdenum testing. The concentrate was

consistently contaminated with pyrite, resulting in low concentrate grades.

As per normal plant practice, tailings water in the pilot was recycled to the

primary grinding mill. The addition of a pyrite recovery circuit and reagent

(PAX) to recover pyrite was believed to have been the source of the problem.

In an effort to derive some basic copper-molybdenum separation data, the bulk

concentrate was further cleaned to reject pyrite. This concentrate was combined

tested using a conventional copper-molybdenum separation process. The results

should be used with caution as the bulk concentrate was essentially

unrepresentative due to the additional cleaning stages.

APPENDIX I – KM3512

SAMPLE ORIGIN

1

1.0 Sample Origin

On July 19, 2012, half drill core intervals from several drill holes were received at

ALS Metallurgy Kamloops for testing. The total weight of the shipment was

approximately 3,524 kg. The drill core was identified by drill hole and sample ID

number. Each sample was weighed; Table I-1 displays the details of the samples

received and their respective weights.

Based on instructions from the client, select intervals were crushed and screened

to 6 mesh in preparation for compositing. Five separate composites were

constructed for testing; three hypogene composites for bench testing and two for

pilot plant testing. The details of the composite construction are displayed in

Table I-2.

Not all of the drill core was used, some intact drill core intervals were retained in

storage.

The hypogene composites used for laboratory testing were homogenized and

rotary split into 2 kg charges for metallurgical testing. The charges were sealed

into plastic bags under nitrogen. These samples were stored frozen until their

subsequent use in the test program. Representative head assays of the composites

are displayed in Table I-3.

The pilot plant samples were crushed and screened to pass 5 mm. The samples

were blended with a mechanical loader using a cone and quartering method. The

samples were stored in plastic totes at ambient temperature prior to processing in

the pilot plant.

A commissioning composite was constructed from old test sample. This material,

approximately 1,353 kg, was used to calibrate the grinding and mass flow rates in

the pilot plant.
